10. (9 points) According to the U.S. Bureau of Labor Statistics, this was true in the U.S. in August 2009:
Unemployed people:       14,928,000
Employed people:        139,649,000

Calculate the August 2009 U.S. unemployment rate and write it in the underlined space provided below:
(Use the underlined space provided and show your calculations--or receive no credit for your answer)

                                                                                              __9.6573__%
14928000 / (14928000+139649000) = .096573 = 9.6573%




11. (9 points) Draw a graph of the steel market that shows the effects of a Pigouvian tax on the steel market. Fully label
your graph.




12. (9 points) Using two or more content-rich sentences, discuss why the quantity of capital is important to an economy’s
long term economic growth. Please be very specific in your discussion if you want credit; I do not like BS answers.

        Capital—machinery and buildings used by workers—helps increase the labor
productivity of workers. For example, robots on an auto assembly line result in an
increased amount of cars produced by a factory and its workers. Increased labor
productivity results in an increase in the amount of goods that an economy can produce;
this is the definition of economic growth—greater production of goods and services.




                                                                                                                             4
13. (8 points) Use some of the information provided here about a fake economy to calculate the fake economy’s GDP.
(Show your calculations, or receive zero credit for your answer.)

        Personal consumption expenditures         2000                      Wages and salaries       3200
        Gross private domestic investment         900                       Exports                  1000
        Imports                                   300                       Corporate profits        400
        Depreciation                              80                        Government purchases     500



    GDP = 2000 + 900 + 500 + 1000 – 300 = 4100



14. (8 points) Does getting a flu shot cause a negative externality or a positive externality? Carefully explain, and
describe the specific negative or positive externality caused by the flu shot. Please be very specific in your description if
you want credit; I do not like BS answers.


Positive externality. If a person gets a flu shot, she is less likely to become infected with the
flu. This benefits other people. Other people benefit because the person who gets the flu shot is
less likely to get the flu, so she is less likely to make other people sick by giving them the flu.
   The positive externality is: other people are less likely to catch the flu from a person who gets
a flu shot.



15. (8 points) List the four steps used by the Bureau of Labor Statistics when they calculate the CPI and inflation. (Just
list the steps; no explanation is required.)


Step 1: The consumption basket is determined
      Step 2: Prices are surveyed from the market.
      Step 3: CPI is computed from the cost of basket.
      Step 4: Inflation is computed from CPI




                                                                                                                                5
